To all whom it may concern.-

Be it known that I, SAMUEL Voss, a subject of the King of Prussia, German Emperor, and a resident of 107 Wilmersdorferstrasse, Charlottenburg, near Berlin, Kingdom of Prussia, German Empire, have invented a new and useful Device for Setting Freestones, of which the following is an exact specification.

My invention relates to a device for setting freestones, and has for its purpose to provide a device which allows a moving of the stones along the wall of the building without any scaffolding being in the way.

The invention consists, essentially, of a vertical mast movable along the wall of the building. l

For setting freestones Vscaifoldings have been hitherto used, which mostly render the raising of the stones diflicult on account of the struttings of the scaifolds being on certain places in the way. Other constructions of scaffoldings which are free from this disadvantage project into the interior of the building, so that the inside of the building` cannot be completed before the front wall is ready--that is to say, before the scaifoldings are removed. All these disadvantages are done away with by the construction forming the object of the present invention, which is illustrated in the accompanying drawings, in which-l Figure l is a front view of the device. Fig. 2 is a side view, and Fig. 3 a plan of the same. Figs. 4 to 7 show detailed parts in an enlarged scale. c

In the drawings, a is a verticalI mast resting upon a roller m. This roller m runs upon a rail u, situated along the'front side of the building. The mast a is provided on its upper part with a vertical arm c, upon which runs a small trolley 0, indicated in the drawings by small rollers. The cross-section of the mastla may be seen from Fig. 5; but it will be understood that according to the strength to be obtained any convenient other cross-section may be more advantageous. It will be clear that the cross-section of the mast must be as'small as possible, so that the mastv to the mast a, upon which platform the windlass e for raising the load is situated.

For guiding the mast in the direction vertical -to the rail n a scaffold consisting of the posts ff and the horizontal beam g is provided. The horizontal beam g consists in the construction shown of two angle-irons p and q, connected by means of an iron plate 1". The mast r is guided by means of rollers /t and z', Figs. I and 5, running along one of these angle-irons Q. The rollers c' serve for preventing an overturning of the mast on account of the load or of the wind-pressure. Advantageously two rollers-z' are provided. The roller /t only serves for taking up a windpressure coming from the side of the building, and it will therefore be sufficient to provide only one ofthese rollers. The horizontal beam c7 is advantageously arranged so as to pass through the mast, which can easily be effected, as the mast consists of lattice-work.

For preventing an overturning of the mast in the direction vertical to the above directionfthat is to say, in the direction of the rail qt-ropes Zo are provided, which ropes run over rollers Z and m, provided at the mast, and which are fixed to the upper ends of the posts f. These ropes allow in the well-known manner a moving of the mast and prevent at the same time an overturning of the same in the direction of the rail n.

The ropes, which are fixed, as mentioned aboye, to the upper ends of the posts f, run around the rollers Z and the roller m at the bottom of the mast rto the bottom of the opposite post f. The roller m is for this purpose provided with three grooves, as will be seen from Figs. 6 and 7, the middle groove running upon the rail n and the side grooves serving for guiding the ropes 7c.

It will be clear that the scaffolding f y, which serves for guiding the mast, can be easily constructed, so that the same is not in the wayin raising the stones. In the example shown in the drawings the postsj1 consist of framed work situated'in -two planes for offering suiicient resistance to an overturning'of'the mast. If` necessary, the scaffolding may be loaded for augmenting the stability ofthe same.

IOO

Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States is- 1. In a device for setting freestones, the combination of a vertical mast, a windlass iixed to this mast and a scaffolding for guiding this mast, said scaffolding consisting of two vertical posts connected by a horizontal beam, substantially as described and for the purpose set forth.

2. In a device for setting freestones, the combination of a vertical mast, a windlass fixed to this mast, ascatfolding for guiding this mast,said seaolding consisting of two vertical posts connected by a horizontal beam1 said beam passing through the mast, substantially as described and for the purpose set forth.
